Virtual Memory too low Warning Trouble in win xp and vista

When there is less physical memory than needed, then some virtual memory (virtual RAM) is created on the disk. When there is a limit set to the size of virtual memory usage and there is not enough of it present there is a warning that frequently comes “Virtual Memory too low”.

Solution 1 :
This problem occurs when physical RAM + Virtual RAM (usually created on hard disk) together are not sufficient to take care of the currently needed RAM size, or this situation is about to arise. This usually happens when some fixed upper limit for Virtual Memory has been set. To solve this problem, you can either upgrade you physical RAM on your computer (recommended), or you can set the Virtual Memory to system managed size or you can do both. Setting Virtual Memory to system managed size means windows will set it to higher size whenever needed automatically,for this,


Right click on My computer --> goto properties, goto advanced tab, click on performance settings, now click on advanced, now click on advanced, now click on change button for Virtual memory.

On this screen select the System managed size, press OK. After this re-start your computer. This will solve the virtual memory too low problem.

Solution 2: Recommended solution is to upgrade your physical memory (RAM) according to requirements of the kind of applications that you run on your computer. If you upgrade RAM or not, the following procedure will help prevent this warning by increasing the virtual memory limit.
  • Right click on My computer icon and click properties.
  • This will show system properties window. Click on a advanced tab and click on the settings button under heading performance.
  • This will open performance options window. Click on advanced tab and click on change button under heading virtual memory.
  • Check if the space available is set to some custom value or double the RAM size ?
  • If it is not double the RAM memory size , then select the size option set the virtual memory size double the RAM Size and press set button and press OK button.
  • Restart the computer.

How To Uninstall GrooveMonitor.exe

GrooveMonitor is a service utility that tracks groove behavour and creates reports for error reporting to MS (what else does it report?). It loads on startup. It gets installed when you install Office 2007. However it doesn't get uninstalled when you uninstall Office 2007. GrooveMonitor starts upon Windows startup (via registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).
To remove GrooveMonitor from your machine you have to go to Control Panel and then select Add/Remove programs. GrooveMonitor is one of the displayed applications. Uninstall it from there. That should do it for any normal windows program. Not surprisingly Microsoft himself often violates this basic principle (which surprisingly would give you more control over their crappy [pardon my French] software), and GrooveMonitor will still load on startup.
You can however use msconfig to prevent it from coming up on Windows startup.
1. Go to Start menu and click Run
2. Type msconfig and press Enter.
3. Go to Startup tab and then uncheck any reference to "groovemonitor"
4. Reboot
Note: Some malware may also camouflage themselves as GrooveMonitor.exe, particularly if they are located in c:\windows or c:\windows\system32 folder.
GrooveMonitor is currently owned by Microsoft Corporation.

Disable USB Ports

Here is a way to disable USB ports in an Active Directory Domain


In Active Directory Users and Computers, open an existing GPO or create a new one and open it. Use the security settings of that GPO to specify which computers it affects.

In that GPO, go to Computer Configuration – Windows Settings – Security Settings – File System and create a new entry (right-click File System and select Add File). Specify the location of USBSTOR.INF (usually SystemRoot%\Inf\USBSTOR.INF)
Change the security settings of the new entry. The security settings that you specify here will be enforced on the USBSTOR.INF of every computer to which the GPO is applied. This process is not additive, which means that the previous security settings of USBSTOR.INF will be overwritten by the ones given in the GPO. It is therefore recommended to grant full control to SYSTEM and local administrators. But unlike in the default security settings of USBSTOR.INF, you should not grant any priviledges to Everybody. You do not need to explicitly deny access – just omit an entry for Everybody. Optionally, you can grant read access to a certain group. Members of this group will be able to use USB storage.

Repeat the above two steps for USBSTOR.PNF.

Download USBSTOR.ADM.

Back in the GPO, right-click Administrative Templates under Computer Configuration and select Add/Remove Templates. Click Add and browse to the location of USBSTOR.ADM. Close the dialog.

You should now have an additional entry called Services and Drivers in Administrative Templates. Click on it. If it is empty, select View from the menu and uncheck Show Policies Only. Click back on Services and Drivers in Administrative Templates. It should now show the USB Storage policy. Double click it, select Enabled and pick Disabled from the Startup Type drop down. Again, the policy must be enabled wheras Startup Type must be Disabled.
Close the dialog as well as the GPO and boot/reboot one of your workstations. Make sure no USB strorage device is connected to that computer. Log on with administrative privileges and check the permissions of USBSTOR.INF and USBSTOR.PNF. Check the value of the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor\Start. It should be 4. It is also ok if the UsbStor key doesn't exist at all.
On the same workstation, log off and back on as a user that should not have access to USB storage. Connect a USB memory stick or a similar device. Nothing should happen. Remove the memory stick.

Log on as a user that should have access to USB storage and execute net start usbstor in a command shell or at Start – Run before connecting the memory stick. The memory stick should initialized and mapped to a drive letter. If USBSTOR fails to start, it's probably because this is the first time a memory stick is plugged into the workstation in which case USBSTOR is not yet installed. Nevertheless, the memory stick should be initialized and mapped correctly but you need to reboot in order to reapply the administrative template such that USBSTOR is disabled again. Alternatively, you can disable it manually by downloading and double clicking USBSTOR.REG as well as executing net stop usbstor.

Instruct the users with access to USB storage that they need to execute net start usbstor before they can connect a USB storage device.
